If it's giving you a filename along with the line number, then it has
executed processing and has reached that line.  It's not possible for
it to be giving you the correct lookup name without processing having
been executed, and the filename calculated at runtime.

I do note that your original message says "rclerk", which of course
has no debugger.  I assume you ran dclerk when you tried to debug it.

Put a "DEBUG ON" just before the lookup and try it again.
